Resoles are usually made from a mixture of phenol and a molar excess of formaldehydeunder basic conditions. Condensation of phenol and formaldehyde in basic medium is carriedout in a series of experiments in order to serve as models in a study aimed at establishing itsstructure rheological characterization when dissolved in acetone. ChemCAD simulationsoftware is adapted in this study in order to design a simulation to the real factory product. Thissoftware simulation is used for the first time in such study. The operation conditions employedin the real production site is tested on this model in order to check its applicability. Thesimulation showed good behavior when the modified manufacturing procedure is applied. Eightsamples of Resole dissolved in acetone are used in this study. Their structure rheologicalcharacterization is carried out by plotting flow curves of different concentration and molecularmass. An important figure in this rheological study namely; the mass of network strand (Me) isobtained. When plotted against concentration (C) i.e. Log Me vs. Log C aslope gave rise to thescaling exponent X, which is a measure of the penetration hindrance. A scaling exponent of0.23 is obtained in this study which is below the value expected for a network with freepenetration. Therefore, partial penetration is expected.
